The circumference of a circle is given by C = 2\pir. Your question asks you to use 3.14 for pi. Radius is half of diameter, so halve those to fit it into the equation.

16). C = 2*3.14*7 = 44.0

17) C = 2*3.14*9 = 56.5

18) C = 2*2.14*12 = 51.4

19) C = 2*2.14*6.4 = 27.4

Find the area and perimeter of the shaded region. Stuck on this one can someone help me
alekssr [168]

Answer:

perimeter-

perimeter outer rectangle = 2 (l+b)

=2×8+9

= 2×17

2×17 =34 cm sq.

perimeter of inner rectangle = 2 (l+b)

= 2×5+3

=2× 8

= 16 cm sq.

perimeter of shaded portion= 34 - 16

= 18 cm sq.

area-

<em>area</em><em> </em><em>of</em><em> </em><em> </em><em>inner</em><em> </em> rectangle =l×b

l×b = 3×5

3×5=15

15 cm sq.

area of outer rectangle =l×b

l×b= 9×8

9×8= 72

72 cm sq.

area of shaded portion = 72 -15 =57 cm sq.

hey there! In second method i have done first area of inner rectangle but you have to do first area of outer rectangle...

hope it helps you....
